Lots of signs: “Tenant Parking Only” ones in the sidewalk flower beds, plus two “No Parking” notices cast in raised letters on the sidewalk. Her staff even took it upon themselves to paint the curb yellow.

All that work to deprive the little people of their right to park on a public street — even though the pop queen’s townhouse has two garages.

Happily, an outraged neighbor called the Department of Transportation, which in turn issued a “letter of defacement” demanding she change everything back to normal within 30 days.

On the other hand, DOT only threatened a $250 fine, which we’re pretty sure Madge can afford. Let’s hope she realizes that just paying up would be a mistake.

She might also want to consider a staff shakeup: Her spokesman actually tried to claim the street alterations were “up to New York City code” — though several of the fakes were copies of California signs.

Neighbors also report that the Material Matron’s staff blocks foot and street traffic when she leaves her digs to protect her privacy.

Definitely over the borderline, ma’am. Better find a different way to express yourself.
